of the part 7 isfintern'al'ly threaded,"asiat 1Q, to engage .the threadedportion 4 ofthe part 3, butthesefthreads `10 `are Vpreferably cut away at the rinnerjeiidof 'fthe part' adja-'L cent 'tlilejvvebv 8,' as at 11),"asj shownin Fig. 2, toenlarge'thechamber at its bottoni,- so that the'thr'eadsyof the partf5jwillfonly engage the threads 10 until allof thenthre'ads 10 have been' -moved past'tlielthreads 6, whereupon thep'art 5`may have 'a limited movement `axially ofthe part 7. In lthis mann'e'rthe `likelihood oflosing .the part 5 is obviated and the eas'efof "assembly is increased. f l

Arranged' lin an annular vseries about the peripheryfof the upper and, lower vvparts of Fig.` 7 is a side elevation of the j'upper the member 7 are lugsor projelctions"13 and 12, 12 respectively, wherebya Spannerv wrench; or otherrequivalentmeans may be used for tightening or'vloosening ythe parts." The lugs12aref similar to thelugs 1 2, ein` cept that'theside edgesthereo'fare inwardly beveled so as tofforman outwardly divergent wedge-shaped lug for a purposel to'be more particularly described. 1 Y

The tubular part 18, somewhat similar to the part 7, is' adapted to be secured tothe part 2so`` as tohold the gland 5in place,

saidpart 18 being cut awayat vthelower lio portion of its threaded part similar to the cutaway portion 11 of the part 7 and for the `same purpose. An annular series of lugs 19 are arranged about the part 18.

In order to prevent relative rotation between the parts 7 and 18, I have provided one or more keys extending between and engaging said parts, each of said keys provided with a portion 14 engageable between the adjacent lugs 19 of the part 18, as shown more clearly in Fig. 3, and having an offset portion 15 at the lower end of the portion 14 adapted to seat upon the annular upper edge of the part A7 as shown in Fig. 2. A pair of prongs or legs extend from the outer edge of the part 15 in a plane parallel to the portion 14, providing a space 17 between the legs. The legs 16 are arranged on either side of the beveled lugs 12, as shown more clearly in Figs. 8 and 9, so that when the keys are in position there can be no relative rotation between the parts 7 and 18. A screen or other suitable material 20 is arranged about the portions 111 of the keys in orderto prevent dust or other foreign mat.- ter from reaching the swab or absorbent material 9; as well as preventing the swab from being blown out or displaced.

Any suitable means may be provided for supplying oil orother lubricant to the swab absorbent material 9, but I have found it preferable to provide an oil cup 21, secured to the portion 2 of the engine or pump by means of a bracket 22, or other suitable or equivalent device, the outlet of the oil cup having a duct 23 leading therefrom and through the screen 20, so as to deliver lubricant to the absorbent material 9.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

TWhat I claim as new and desire to secure by Letters Patent is:

1. A lubricator for a reciprocating element comprising a hollow member having a threaded portion surrounding said element, a tubular member within Asaid member and slidably encircling said reciprocating element and provided with a threaded portion at one end engageable with said first-mentioned threaded portion, said hollow member constructed to permit a limited axial movement of said second-mentioned member when assembled, but preventing the accidental separation thereof.

2. A lubricator for a reciprocating element comprising a hollow cup-shaped member having an internally threaded portion surrounding said element, a tubular member within said member and slidably encircling said reciprocating element and having an externally threaded flange at one end cooperating with said lirst-mentioned threaded portion, said hollow members so constructed to permit a limited axial movement of said second-mentioned member when assembled and preventing accidental separation of said members.

8. A lubricator for a reciprocating element, comprising a hollow cup-shaped member provided with a radial web intermediate its ends to form a pair of spaced chambers, one of said Vchambers threaded and sur. rounding said reciprocating element, a tubular member within said chamber to provide a packing for said reciprocating part and having an externally threaded flange at one end engageable with said lirst-mentioned threaded portion, the bottom of said chamber enlarged in diameter whereby said second-mentioned tubular member may have a limited axial movement relatively of said cup-shaped member when assembled but preventing accidental separation of said parts, and means for conducting lubricant to the other of said chambers.

A. In a rod swabbing device of the kind described and in combination, acup-shaped member provided with an opening therethrough of a size to slidably lit the rod to be swabbed, an oil swab arranged in said cup, and a swab retaining member enclosing the swab but permitting circulation of air about the rod.

5. In a device of the kind described land in combination, a reciprocating element to be lubricated, axially spaced packing means adapted to receive said element, one of said packing means provided with an oil chamber therein communicating with said element, a plurality of circumferentiallyarranged locking means extending between said packing means for preventing relative movement therebetween, and a screen secured about the exterior of said locking means. I

6. In a device of the kind described and in combination, a reciprocating element, packing means spaced thereon and provided with lugs circumferentially spaced about their peripheries, and keys extending between said packing means to prevent relative rotation therebetween, each of said keys comprising a part engageable between adjacent lugs of one of said members and having its opposite end straddling one of the lugs of the other packing means.

7. In a device of the kind described and in combination, a reciprocating element, packing means spaced thereon and having lugs circumferentially spaced about their exico teriors, keys extending between said packing f means to prevent relative rotation therebetween, each of said keys comprising a part engageable between adjacent lugs of one of In testimony whereof, I have hereunto said members and having its opposite end signed my name in the presence of two substraddling one of the lugs of the other paeksoribing Witnesses.
